RIKEN VITAMIN Co., Ltd. RIKECOLOR YG

Riken Vitamin Co., Ltd. Rikecolor YG is obtained from the fruit of Gardenia jasminoides Ellis. It is a water soluble yellow color with Crocin, which is the same ingredient as Saffron yellow, as its principal-ingredient. From long ago, Gardenia jasminoides Ellis was used as a herbal medicine and food color in Asia. Today, Crocin is widely used as a food color in Chinese noodles, pastry, desserts, and confections. Crocin yellow color may turn green if it is used in fermented food and food made of flour. The cause of this color change lies in Geniposide, a type of iridoid glycoside, which becomes blue through enzymatic reaction. This blue color and Crocin yellow color combine to produce the green color. The RIKECOLOR YG series employs a special method to separate Geniposide and is produced under consistent production control. Thus, the food color does not turn green and has a fixed-quality yellow color.
